Objective To observe the proportion changes of CD4+CD25+FOXP3+ T cells in peripheral blood of patients with Vogt-Koyanagi-Harada disease(VKH)before and after one month of treatment. Methods The peripheral blood samples from 15 patients with VKH disease before and after one month of treatment by glucocorticoid,and from 15 healthy volunteers were collected,and lymphoeytes were separated from them.CD4+CD25+regulatory T cells were Iabeled by antibodies of cell surface marker CD4、CD25 and transcription factor FOXP3.The proportion of CD4+CD25+FOXP3+ T cells were detected by flow cytometry. Results Before the treatment,the percentage of CD4+ CD25+FOXP3+ T cells in periphery blood was(0.30±0.19)%of CD4+ cell in VKH patients,and(1.41±0.52)%in control group,the difference was statistically significant(t=7.665,P＜0.01);after one month of treatment,the VKH patients group was(1.28±0.54)%which close to the control group.However there were two patients whose CD4+ CD25+ T cells inereased extraordinarily after one month of treatment. Conclusions The proportion of CD4+ CD25+ FOCP3+ T cells in periphery blood in VKH patients were lower than control group obviously before treatment,but were close to eontrol group after treatment.Those results indicated that VKH diseases may be associated with the decreased proportion of CD4+ CD25+ regulatory T cells.

Purpose:To study the methods of treatment of spinalcord implanation medulloblatoma with combined chemotherapy. Methods:Teniposide (VM 26) 100 mg/day (dissolving in 250 ml physiological saline(N.S.)) was injected intravenously in 3 consecutive days. And it was repeated after a 7 day interval, and bleomycin A 5(PYM) 4 mg (in 250 ml N.S.) was intravenously injected twice a week. Methotrexate (MTX) 10 mg (in 5 ml N.S.) and dexamethsone 3 mg were injected intrathically once a week. The whole treatment included 5 courses and lasted about one and half month.Results:The study involved 6 cases. MRI, whick were performed 2 weeks after the treatment, showed tumors disappeared in 2 cases and 80% shrunk in 4 cases. The tumors completely disappeared after repeated treatments in the 4 cases. Conclusions:Combined chemotherapy is an efficient alternative treatment for spinalcord implanation medulloblatoma.

Drug delivery system in tumor targeting research has always been a difficult problem.Apoptosis in vitro experiments and body pharmacokinetic experiments can not reflect the targeting of drug delivery system indirectly.Imaging techniques both in vivo and in vitro solve the problem,researchers can not only observe the drug delivery system in the target organ,the target tissue and target cell directly,but also analyze quantitatively and qualitatively.

Objective To study knowledge,ability and related behavior of reproductive health among unmarried women migrants in Qingdao area,Shandong and evaluate effectiveness of basic intervention,including provision of free condom and health education and enhanced intervention,including healthy sex,contraception and health-care seeking behavior.Methods A community intervention trial was conducted among 1800 unmarried women migrants aged 18 -29 years in 10 workplaces of Qingdao.Basic intervention included health knowledge publicity and distribution of free condoms,and enhanced intervention included distribution of very important person (VIP) service cards,hotline telephone service,broadcasting digital versatile disc (DVD) of reproductive health knowledge,health lectures,peer education,and so on,in addition to health knowledge publicity and distribution of free condoms.Effectiveness was evaluated using questionnaire before and six months after intervention.Results After intervention,awareness of reproductive health and attitude to reproductive health improved significantly among the women migrants,as compared to those before intervention,particularly in knowledge of contraception and sexual health with enhanced intervention (with more than 20％ of them aware) ( P ＜ 0.01 ).About effectiveness on health-care seeking behavior,59.2％ (482/814) and 80.8％ (651/806) of the women migrants with reproductive tract infections would visit physicians after basic and enhanced intervention,as compared to those of 32.0％ (286/895) and 31.9％ (275/862) before them,respectively (P＜0.01).About effectiveness on contraceptive behavior,persistent and proper use of effective contraception methods improved significantly after intervention,as compared to that before it ( P ＜ 0.05 ),but with no significant difference between the two group with basic and enhanced intervention.Conclusions Both basic and enhanced intervention is effective and feasible in women migrants,more effective for enhanced one.

Objective To observe the effects of drainage with vacuum and closure (VAC) on acute wounds, and explore the mechanism of drainage with VAC in promoting wound healing.Methods Twenty-four acute wounds were inflicted on the backs of 12 New Zealand white rabbits (each rabbit two wounds), and the rabbits were divided into a drainage with VAC group and a control group randomly. The drainage with VAC group was treated with drainage with VAC. The control group was treated with wet saline gauze. The wounds were observed 3 and 7 days after treatment. Patho-morphological changes in tissues from the compressed area were observed by HE staining. The expression level of Cx 43 mRNA was detected using a RT-PCR.Results At the 3rd and 7th day after treatment, the wounds of the drainage with VAC group were clean, fresh and had less edema compared with those of the control group. Pathomorphological tissue changes were more obvious in the drainage with VAC group. The expression of Cx 43 mRNA in the drainage with VAC group had declined significantly compared with the control group.Conclusion Drainage with VAC can promote inflammatory cell infiltration, down-regulate the expression of Cx 43 mRNA, and promote wound healing.

Objective To evaluate the clinical efficacy of thoracoscopic surgery combined with chemorad-iotherapy in patients with N2 stage ⅢA non-small cell lung cancer (NSCLC). Methods 40 patients (study group) received thoracoscopic surgery and another 40 patients (control group) received traditional thoracotomy. Combination therapy with navelbine and cisplatin were postoperatively administered for four cycles and one cycle lasted for 3 weeks. 7 to 14 days after chemotherapy , sequential conformal radiotherapy were delivered. The one-year survival and two-year survival rates , duration of tatal treatment , and adverse reactions were compared between the two groups. Results In the study group, duration of total treatment time and time to postoperative chemotherapy were significantly shorter (χ2=9.45,P=0.002 andχ2=41.324, P=0.000), and the KPS score was significantly higher (χ2 = 15.118,P = 0.002). No significant differences were found between the two groups in bone marrow suppression,gastrointestinal reactions,and one- or two-year survival rate. Conclusions As compared with conventional surgery,post-thoracoscopic surgery sequential chemoradiotherapy for patients with N2 stage ⅢA NSCLC could achieve a better efficacy with less surgical trauma , shorter hospital stay , faster recovery , and shorter time to postoperative chemotherapy and total treatment duration;it is worth further researching and popularizing.

Objective To investigate the short and longterm effect of the treatment on acute coronary syndrome(ACS) with percutaneous coronary angioplasty and stenting.Methods 65 patients suffering from ACS were treated with angiography to illuminate the features of lesions and proceeded with percutaneous coronary angioplasty and stenting when the angina was not completed controlled with internal medicine.All patients were treated with a new anti-thrombotic regimen,including aspirin,ticlopidine or clopidogrel, and low-molecular-weight heparin.Results The rates of success for patients and lesions were 96.9% and 82.7% respectively.One patient died without myocardial infarction or emergency bypass surgery.56 patients had no symptom of angina after procedure,and 5 patients had non-typical chest pain which disappeared within 2~3 days.During the 3~54 month follow-up,one patient died,one patient developed myocardial infarction and 4 patients underwent target vessel revascularization(repeated angioplasty 2 and bypass surgery 2).Conclusions With the widespread use of aspirin-ticlopidine-low molecular heparin regimen,ACS patients can undergo PTCA and stenting with high success rate,excellent immediate efficacy and long-term efficacy.

Objective To evaluate the efficacy and safety of consolidation chemotherapy after thoracic radical concurrent chemoradiotherapy for patients with oligometastatic non?small cell lung cancer ( NSCLC) . Methods Sixty?six NSCLC patients with more than five metastases from 2008 to 2013 were enrolled, and image?guided radiotherapy with conventionally fractionated or hypofractionated doses were performed for these patients. Platinum?based doublets chemotherapy was applied for both concurrent chemoradiotherapy and consolidation chemotherapy. Short?term outcome, adverse reactions, and survival rate were assessed for the patients after treatment. Results Sixty?four patients completed the treatment. The median biologically equivalent dose for planning target volume of thoracic primary tumor lesions was 72 Gy, with a median number of chemotherapy cycles of 4. The objective response rate for thoracic lesions was 70%. The follow?up rate was 97%. The 1?, 2?, and 3?year overall survival ( OS) rates were 72%, 53%, and 31%, respectively, with a median OS time of 25 months;the 1?, 2?, and 3?year progression?free survival ( PFS) rates were 56%, 26%, and 7%, respectively, with a median PFS time of 14 months. The incidence of grade 2?3 acute radiation pneumonitis and radiation esophagitis was 1% and 17%, respectively, and the incidence of grade 3?4 decreases in leukocytes, hemoglobin, and platelet count was 39%, 11%, and 16%, respectively. Conclusions Radical radiotherapy combined with concurrent and consolidation chemotherapy for oligometastatic NSCLC can achieve good short?term outcome and long?term survival, with tolerable adverse effects.
